WARNING:
    --------
    This hex dump is shown only to help the reader understand how IFF
    chunks appear in a file.  You cannot ever depend on any particular
    ILBM chunk being at any particular offset into the file.  IFF files
    are composed, in their simplest form, of chunks within a FORM.  Each
    chunk starts with a 4-letter chunkID, followed by a 32-bit length of
    the rest of the chunk.  You must parse IFF files, skipping past
    unneeded or unknown chunks by seeking their length (+1 if odd length)
    to the next 4-letter chunk ID.  In a real ILBM file, you are likely
    to encounter additional optional chunks.  See the IFF Specification
    listed in the Amiga ROM Kernel Reference Manual: Devices for
    additional information on such chunks.
